Back/Forward - general solidity about lyt

BTW jumping subsections reminds - aspiring to assimilates - jumping by clicking on the audio statusbar. Which seems to work seamlessly. If we want to implement it easily (for no other reason than knowing it works if we need it), why not fake a timeswitch?

I'm not sure I completely understand what you mean. As you say, it's difficult unless we're using the same terms.

Here's what I've been calling things so far (and this is what it's called in the code, too):

1. Section refers to anything with its own heading (regardless of level) in the NCC file. Sections map 1:1 to SMIL files, and thus 1:1 to MP3s. Sections can be nested, but they are still played back separately.
2. Segment refers to a time-slice in a section's MP3 file. This is the smallest "unit" in the system.

It's confusing to call something a "chapter" because we can't tell from the structure of an NCC if something's literally a chapter or not. E.g. the back cover of the book isn't a chapter, but it is a section.

Right now the back/forward buttons skip through segments, until it reaches the start/end of the current section. At the point it'll skip to the previous/next section, and then skip through that section's segments.

Things get confusing/hard to code because books are divided in different ways. Sometimes several time-slices will refer to the same piece of text or the same panel in a comic book; sometimes it's 1:1. Sometimes the whole book is divided neatly into "1 section per chapter", and other times it's divided into "everything in 1 section".

None of this is a problem if you're reading the book, and just want to play something as audio (and everything is a local file with zero download time). If you're just reading, you can alway drill down to the piece(s) of audio that belongs to a given piece of text.
But we're doing the opposite: Playing back audio, and showing the text. And that's makes everything about the Daisy system maddening.

Anyway, let's talk more about this on Monday
